t (s) v (m s−1) 0 3 9 10 T 0 0.9 The velocity of a particle at time t s after leaving a fixed point O is vms−1. The diagram shows a velocity-time graph which models the motion of the particle. The graph consists of 5 straight line segments. The particle accelerates to a speed of 0.9ms−1 in a period of 3s, then travels at constant speed for 6s, and then comes instantaneously to rest 1s later. The particle then moves back and returns to rest at O at time T s.
